One of my remaining bits of snobbiness is I judge people if they only read one genre. I know it's not fair of me, and people read for different reasons, but I can't imagine actively seeking out the tropes that I want to read ahead of time.

I wish I did. My instinct is it's pretty weak but that's all I can say.

You could choose a nonstandard infinite natural N and consider the rays at angle 2pik/N, where k ranges over the N*. For each ray take the coordinate that is distance 1 from the origin. Make the nonstandard polygon with these vertices. Then collect the reals that are near the polygon.

It was fun to figure out how to topologize the ordered compact subsets and the resulting spaces have some really interesting properties.

An Adaptation of the Vietoris Topology for Ordered Compact Sets We introduce a natural topology on powers of a space that is inspired by the Vietoris topology on compact subsets. We then place this topology in context with other product topologies; specifically, w...

I've got a new paper that I'm proud of: arxiv.org/abs/2507.17936. While teaching discrete math, we got some results about the topology of finite subsets, finite tuples, and compact subsets of a given space. I was teaching combinatorics, so I wondered about ordered compact subsets. This is the result

I can see why you were frustrated trying to make that. It's a really nice end result though, congrats!

AI companies are just like every other profiteer horning in on public education money. They aren't trying to fool educators, who know better. They're trying to fool politicians, who are stupid af and easily bought.

Everyone's experience is different, but I quit caffeine about a year and a half ago and it really helped my anxiety symptoms. I love coffee but apparently my brain didn't.

Today was my first day at a non academic job since I earned my PhD.
Academia turned out to be a corrosive environment for me, but I hope to continue my research as a hobby now.
I'm hopeful that I can thrive in my new work environment and also do some good for the world.

This. As educators we can easily get too big of a head and take a student's word that we were the first person to ever show them something.
I think it's better to give both the student and their former teacher the benefit of the doubt.

the sham legacy of Richard Feynman
YouTube video by Angela Collier the sham legacy of Richard Feynman

I found this to be a really interesting video. A good attempt to separate Feynman the man from his stories and his physics. Also an indictment of the popular science publishing industry.

Cover of a book titled "Exploring Complex Survey Data Analysis Using R" by Stephanie Zimmer, Rebecca Powell, and Isabella VelΓ‘squez. Illustration is in the style of a fantasy map, but with data represented throughout the landscape. For example, mountain ridgelines are line charts, buildings create a bar chart, a farmer's fields make up a contingency table, light lightposts are lollipop charts, etc.

I absolutely loved working on this cover art w/ @statsteph.bsky.social, @ivelasq3.bsky.social, & Rebecca Powell! Fantasy maps + data? What a dream.

Have any of y'all ran a senior seminar/independent study in set theory before? I'm running one this fall with an interested, talented student who lacks any real set theory experience.
Any advice you have is appreciated.

In honor of the Chinese remainder theorem, I'm going to refer to Newton's method as the British root approximation theorem from here on out.

It's traditionally a very packed class. Vectors, functions from R to R^3 going up to TNB frames for some reason, functions from R^3 to R with optimization and integrals with change of coordinates, oh and then cover Stokes theorem.

It's a mess.

But what if you have to do that exact specific thing later? Better keep that regex.

Fortunately, the quality of his writing is pretty good too from what I recall. It's not part of a story, but his note about his friends who died from drug abuse at the start of a scanner darkly really gets me.

Inside of you are two numbers that are transcendental. We know at least one way of combining them is also transcendental. That might be you.
